I have been using baking soda for my Alk for a while now and have used it many times in the past i have followed Randy's formula and bake 1 box ( 16 oz ) and dissolve this in 1 gallon of R/O . Now i don't let my container get too low before i make another batch , after adding new solution the next day i get a large ALK swing ??
i use the same amount of baking soda , same measuring container , same temp R/O water , mix it the same and let it sit the same before adding to container for dosing .. now i try and use a Hanna Alk checker on the solution i have been dosing and the new solution to get them to match potency but i believe the Hanna checker tops out at 20 ? is there something im missing to why the big swing in Alk if im doing everything the same every time im mixing ?
something else easier i can use for Alk that wont break the bank ? i dose approx. 800ML in 24hr to keep Alk around 8.2 ( 34ml hr )
